Step 5: Create POJO Classes 
Step 6: Create DAO Classes : Create an interface/classes for accessing the MySQL Database
Step 7: Create Service
Step 8: Create Controllers
Step 9: Create ApplicationConfig
Step 10: Create check-out using Spring work flow
Step 11: Using Spring Security for Authentication and Authorization
